Well well well. You know, I certainly looked back over my 26 years with my ex and wondered, were there more affairs that I didn't know about? I'll never know now - but def some suspicions.
In the end, I think you do have to ask yourself - what would it take, if he comes back to the relationship, for you to feel entirely secure?
In my case - when my ex finally left - I realized that there really wasn't ANYTHING he could do at that point, that would ever make me feel safe with him again. After two affairs, two reconciliations, and him leaving without really trying at the end - I realized I would always be looking over my shoulder if we reconciled again. And I didn't want that.
